Rachelle was born in Manila, Philippines and is of Chinese descent. Fondly called Shin or Shin-Shin by her friends, Rachelle’s interest in singing started at a very young age. Her father predicted even before she turned a year old that she was destined to be a singer. As a child, she showed signs of having a flair and passion for music. When she turned six, she underwent vocal training and lessons and, by the time she was nine, she participated in her very first amateur singing competition and won the first prize, belting out Jennifer Holliday’s “And I Am Telling You,” in spite of being the youngest contender.
